Description
Technical field
The embodiment of the invention relates to moving communicating field, relates in particular to a kind of method of messaging in routing non-access layer.
Background technology
E-UTRAN (Evolved UMTS Radio Access Network, E-UTRAN) be called long-term evolving network (Long Term Evolution again, LTE), corresponding core net is System Architecture Evolution (System Architecture Evolution, SAE), particular content can be with reference to agreement 3GPPTS36.300.Evolution base station among the E-UTRAN (Evolved NodeB, eNB) connect by X2 interface between, link to each other by the S1 interface between eNB and the equipment of the core network mobile management entity/gateway MME/S-GW (Mobility Management Equipment/Serving Gateway).The S1 interface of E-UTRAN is divided into chain of command and user's face.The chain of command interface links to each other with MME, is called S1-MME; Interface in the user plane links to each other with S-GW.
In the E-UTRAN network, a S1-MME interface is exactly a SCTP coupling, usually by the network management maintenance system, disposes between eNB and these two peer-entities of MME.Above-mentioned SCTP coupling can be used for carrying several convection current, and this stream is used to carry upper layer communication protocol signaling message, eRANAP signaling message for example, and this message is called S1 Application of Interface part S1-AP message in the SAE/LTE system.
Introduce long-term evolving network base station from home (Long-term Evolution HomeNodeB, LTE HNB) in the E-UTRAN, LTE HNB generally is used for places such as family, office, can help to solve eNB blind spot covering problem.Interface between LTE HNB and the MME/SGW also is the S1 interface.In the zone of a MME control, have the LTE HNB of One's name is legion, each LTE HNB can be connected with a plurality of MME.Closed user group (Closed SubscriberGroup has also been proposed in the 3GPP standard, CSG) notion, a CSG may comprise one or more HNB sub-district, each CSG is corresponding with an access control lists, UE in access control lists can use HNB all among this CSG, and other UE will be rejected access.
Core net node refers to MME and S-GW in the SAE/LTE system, these core net nodes can constitute a resource pool, for example constitutes MME pond, S-GW pond respectively.If access network node eNB and all core net nodes in this resource pool all have be connected, then be called this eNB support S1-flex, specifically can be with reference to agreement 3GPP TS23.236 v8.0.0." territory, pond " refers to when UE moves in this zone, though this UE changes eNB, need not be replaced by the MME of its service, because any one serving MME and all eNB have the S1 interface in this zone.
Signaling message between UE and the MME is called Non-Access Stratum (Non-access Stratum, NAS) message.NAS message will be from the transparent MME that is delivered to of UE, at first need set up RRC between UE and eNB and be connected, and NAS message is carried in the RRC message.
If eNB supports S1-flex, then an eNB may be connected with a lot of MME, and when eNB receives the RRC message of carrying initial NAS message, eNB will select a core net node so, and should initial NAS message to this core net node MME.A kind of method of route NAS message be in the UMTS system the NAS node selection function (NAS Node SelectionFunction, NNSF), NAS node wherein is meant core net node, more detailed content can be with reference to UMTS agreement TS23.236.
After introducing LTE HNB among the E-UTRAN, LTE HNB One's name is legion, if LTE HNB is direct and MME sets up the S1 interface, then have a lot of SCTP couplings on the MME, and the shared overhead of SCTP coupling is quite huge, a SCTP coupling generally takies the 150K byte of memory, and therefore performance, the cost to MME impacts very big.And if just when communication requirement is arranged, just activate the SCTP coupling, then need the regular hour because activate the SCTP coupling, can cause communication delay to increase, systematic function descends.General, a MME can support 1000 macro base stations, i.e. eNB, and can be with 1000 LTE HNB replacement of equal value in macro base station coverage.This just means that a MME may need connect 10 at most
6Individual LTE HNB, promptly a MME need support 10
6Individual S1 interface.
Go up the too many problem of S1 interface in order to solve MME, a kind of scheme of the prior art thinks that as shown in Figure 1, a LTE HNB only supports a S1 interface, just has only a SCTP coupling, and promptly LTE HNB does not support S1-flex, and common eNB supports S1-flex.Do not support S1-flex because of LTE HNB like this, so, having reduced the S1 connection for other MME that are not attached thereto, dotted line represents that the S1 that reduces connects among Fig. 1.But because a LTE HNB only is connected with a MME.When the UE of activated state (when just UE has business to carry out) moves between LTE HNB and eNB, can switch, and this switching may cause reorientation frequent between the MME, promptly the MME that adheres to of UE changes.As shown in fig. 1,, then can stride the switching between the MME, just be reoriented to MME1 from MME2 if the UE of activated state moves to eNB1 from LTE HNB1.
The problems referred to above are present in the UMTS system equally, and in the UMTS system, access network node is RNC, and core net node is SGSN.After introducing HNB in the UMTS system, we are referred to as 3G HNB.3G HNB might have the function of RNC and NodeB in the UMTS, and 3G HNB directly is connected by the Iu interface with SGSN.Have the problem that too many Iu interface is connected with SGSN so equally, if adopt above-mentioned solution to have the problem of SGSN reorientation too.
